Angularjs : Filter conditionaly - angularjs

Question

<div class="district-list" ng-repeat="office in offices | filter : {'DisplayOffice' : officeLocationLevelList.searchText}|limitTo:1">
Have a multilevel list of data. depending on the condition i want to filter the data.(First Level/ inner level). If the first level is selected then i have to search with one json attribute and if the inner level is selected then search with another json attribute. I have set it in a scope variable. How can use scope variable instead of 'DisplayOffice'

Answer 1

you can bind a function to filter which returns the filter condition using scope variables.
angular.module("app", [])
.controller("myCtrl", function($scope) {
$scope.data = [
{
id: 1,
name: 'name1'
},{
id: 2,
name: 'name2'
},{
id: 3,
name: 'name3'
},{
id: 3,
name: 'aaaaa'
}
];
$scope.getCondition = function() {
var obj = {};
obj[$scope.key] = $scope.value;
return obj;
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
Key: <input type="text" ng-model="key">
Value: <input type="text" ng-model="value">
<div ng-repeat="item in data | filter: {[key]:value}">
{{item.name}}
</div>
</div>
and there is another way while using ES6' new feature {[key]: value}, but this may now work for some browsers.
angular.module("app", [])
.controller("myCtrl", function($scope) {
$scope.$watch("key", function() {
console.log({[$scope.key]:$scope.value});
});
$scope.$watch("value", function() {
console.log({[$scope.key]:$scope.value});
});
$scope.data = [
{
id: 1,
name: 'name1'
},{
id: 2,
name: 'name2'
},{
id: 3,
name: 'name3'
},{
id: 3,
name: 'aaaaa'
}
];
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
Key: <input type="text" ng-model="key">
Value: <input type="text" ng-model="value">
<div ng-repeat="item in data | filter: {[key]: value}">
{{item.name}}
</div>
</div>
